No it's not. The 3870 is the one that is almost as fast as a 2900XT.
Anyway, to answer the OPs question...the 3870 is a much better buy....it overclocks very well, is very efficient (power wise), and don't be fooled by the 256bit memory interface...it comes with GDDR4 which can be clocked very high and can still do over 80gbps
Also if you put 2 of these in crossfire they are VERY fast.
